Jeremiah 11:14
So do not pray for this people, or lift up a cry or prayer for them; for I will not hear them in the time that they cry out to Me because of their trouble.

I remember the first time I read this around twenty years ago. I thought it was very harsh for God to tell the prophet not to pray for the people.
God is loving and merciful but will not let sin slide.
There is a future time when He becomes completely intolerant of those that commit sin.
A glimpse of this is in today’s scripture.
Basically, He tells Jeremiah that even if the people cried out to Him, He would not save them because they won’t cry out to Him.
In the future, God punishes those that unrepentantly commit sin by casting all of it away from Him.
I’m sure on the day of judgment many will stand before God and begin making their profession of faith and belief in Him.
They are too late.
Anyone not found written in the Book of Life was cast into the lake of fire. Rev 20:15
There is no mercy for them.
There is no grace for them.
There no longer remains a sacrifice for sins, but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. Heb 10:26-27
However, today you can pray for others.
You can tell them the Gospel.
You can share the hope found in Christ and offer them the opportunity to repent and be saved!
